Sorry for the delay.

What makes the whole thing difficult is that on vanilla 3.6, the problem
happens always, while with vanilla 3.5 it also happens but much less
often - about every 10th suspend / resume cycle.

To test the 3.5 r8169 driver with a 3.6 kernel, and vice versa, I copied
over the r8169.c file, respectively.

The result is that the 3.6 kernel with the "old" driver shows the same
issue as the vanilla 3.6. On 3.5 I also see the same thing happen as
before - every 10th suspend / resume cycle the problem happens,
independent of the "old" or "new" driver.

So the difference comes from the kernel, but finally it is present
anyway. Maybe it is just triggered more efficiently in 3.6? ;-)

Remember that I don't encountered problems with other drivers'
suspend/resume, only with the r8169.

Thanks for considering. Please tell me how I can help further on this issue.
